Air pollution from traffic increases odds of hospital readmission for asthma

27.03.2014

Higher exposure to traffic-related air pollution (TRAP) dramatically increases the odds of readmission to the hospital for asthma – but only for white children, according to a new Cincinnati Children's Hospital Medical Center study.

The study shows that white children exposed to high levels of TRAP are three times more likely to be readmitted for asthma than white children with low TRAP exposure. Levels of TRAP exposure were not associated with increased risk of readmission of black children, despite their having overall higher rates of asthma readmission than white children.

The study is published in The Journal of Pediatrics.

"Although black children in our study had a higher rate of asthma readmission overall, TRAP exposure was not a discernible factor for these children. This suggests that other factors such as social stress or other environmental factors may be particularly relevant in this population," says Nicholas Newman, DO, a pediatrician at Cincinnati Children's and lead author of the study.

"For example, caregivers of black children reported significantly higher rates of psychological distress and were more likely to live in poorer housing conditions, with visible cockroaches or holes or cracks in the walls. These other factors may mask or overwhelm the impact of TRAP in black children."

The researchers studied 758 children between the ages of 1 and 16 admitted to Cincinnati Children's for asthma or wheezing. Fifty-eight percent were black and 32 percent white. Nineteen percent of all children were readmitted within the 12-month period.

TRAP is a complex mixture of chemicals and particles. In urban areas, diesel exhaust particles make up a substantial portion of particles, whose size is linked to their potential for causing health problems. These very small particles have greater potential to be inhaled into the lung, where they can cause swelling that blocks airways.

Exposure to TRAP in this study was estimated using a previously developed model that sampled ambient air at 27 sites in the Cincinnati area between 2001 and 2006. This model was used to estimate exposure for children enrolled in the study based on their home address.

Asthma is the most common chronic disease in children, affecting approximately 7.1 million children in the United States. The estimated annual cost of childhood asthma due to environmental factors, including air pollution is $2.2 billion.

"This study adds to the evidence that TRAP exposure worsens the health of children with asthma," says Robert Kahn, MD, MPH, associate director of general and community pediatrics at Cincinnati Children's and senior author of the study. "We hope that this study can inform public policy. It may also suggest ways to personalize patient care based on environmental risks."

The study is the most recent to be published as part of the Greater Cincinnati Asthma Risks Study (GCARS), which seeks to understand the causes of hospital readmission, particularly for low-income and minority children. The GCARS was funded by support from the National Institutes of Health (1R01AI88116) and the Center for Clinical and Translational Science and Training (NCRR/NIH ULI-RR026314-01).

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
